The diagram compares the interior arrangements of a traditional and a modern Japanese two-storey house.
Overall, both houses are divided into two distinct floors with the same vertical scale and several rooms. The traditional design presents cultural simplicity while the modern presents functionality. Additionally, each traditional room comes with a built-in cupboard to store futons, which is used for sleeping at night.
Concerning the ground floors, a clear contrast in the layout can be seen. In the traditional-styled residence, the small entrance, which connects the gateway to many separated rooms, such as kitchen, bathroom, and a tatami room isolated by walls. In comparison, the modern dwellings feature a large, open-plan entrance, where the kitchen, dining, and living spaces are all merged into one multi-functional area, aligning with the modern lifestyles.
The difference between the two styles of houses is on the upper floor, especially in terms of privacy and sleeping arrangements. In the traditional house, bedrooms follow a classic Japanese style, with tatami flooring, sliding doors, and a place to store futons. One bedroom is placed on the ground floors, while the entire upper level is dedicated to two traditional bedrooms. In contrast, the modern one is divided into three bedrooms, featuring a single main bedroom; all storage cupboards are now eliminated. Instead of limiting bathroom to the ground floor, a pair of bathroom is now relocates upstairs, enhancing sanitary convenience.
